A pendulum is made with a bowling ball as the bob and a wire attached to the ceiling, as shown in the illustration below. The person in the illustration pulls the bowling ball back until it touches his nose, then releases the bowling ball. Assume that he does not move.

1.Describe the changes in the potential energy and the kinetic energy of the bowling ball as it swings back and forth.

2.Explain whether the bowling ball will hit the person's nose. Include a discussion of energy changes in your explanation.

3.Explain what will happen if the person gives the bowling ball a small push as it is released. Include a discussion of energy changes in your explanation.

I dont think anyone is going to give you the answers to this, but they might consider checking it.

can u help bobpursley

The changes in the potential and kinetic energy as it changes is, the potential energy is being prepped first when it is being pulled back. Then when it is released the potential energy is being released. Then when the bowling ball is moving the kinetic energy is being used to keep it in motion

1. The potential energy of the bowling ball changes as it swings back and forth. At the highest point (when the ball is farthest from the person's nose), the potential energy is at its maximum because the ball has the highest height, thus has the most gravitational potential energy. As the ball swings down towards the person's nose, the potential energy decreases and the kinetic energy increases. At the lowest point of the swing (when the ball is closest to the person's nose), the potential energy is at its minimum (zero), and the kinetic energy is at its maximum because the ball is moving the fastest.

2. Whether the bowling ball hits the person's nose or not depends on the initial conditions of release and the length of the pendulum. Assuming the pendulum is set up properly so that the bowling ball will swing freely without any external forces acting on it, the ball will not hit the person's nose when released from the initial position where it touches the nose. This is because the potential energy initially stored is converted to kinetic energy as the ball swings down. The ball will swing back and forth, reaching its highest point on each swing just short of the person's nose due to the conservation of mechanical energy (the total mechanical energy remains constant).

3. If the person gives the bowling ball a small push as it is released, it will have an initial velocity in addition to the initial potential energy. As the ball swings down and then back up, its kinetic energy will increase due to this initial push. The added initial kinetic energy will result in higher velocities during the entire motion of the pendulum. However, if the push is not strong enough, the ball will still swing back and forth without hitting the person's nose, as the energy changes are still governed by the conservation of mechanical energy.
